Certain differences in nutritional characteristics of Polyporus betulinus Fr., Polystictus versicolor Fr. and Fomes pinicola (Fr.) Cooke appeared to be correlated with differences in chemical analyses of Gymnosperm and Angiosperm woods. Worthy of special mention were the water soluble extractives containing simpler carbohydrates and the pentoses in coniferous woods, the commonest hosts of F. pinicola. This organism and also the birch fungus, P. betulinus, showed high reductase activity, a phenomenon reported common in brown rot fungi on Gymnosperm, birch and alder woods. In contrast, P. versicolor, which attacks a wide variety of angiosperm woods in nature, displayed a high oxidase activity and uniform growth on different carbohydrates in artificial nutrient media.
